Hat leider keine Besserung ergeben. Hatte ich auch vorher schonmal versucht, diesmal nur mit der Änderung, dass ich die derbyclient.jar nochmal in die Tomcat-lib eingefügt habe zusätzlich.

[/CODE]
Also ich habe die DB eigentlich "ordentlich aufgesetzt". Hab mir ein Tool runtergeladen, welches mir das Verzeichnis und die DB in meinem Projektordner erstellt hat, dann das Script aus Quartz durchgezogen für Derby. Die Tabellen sind vorhanden.
Edit: BTW, ich hatte vorher eine HSQLDB, die eigentlich genau dieselben Fehler (oder sehr vergleichbare) geschossen hat. Deswegen bin ich auf Derby umgeschwenkt. Eine davon soll es wohl werden, da man die halt embedded laufen lassen kann und nicht extra ne MySQL DB zur Verfügung stellen muss bzw. man könnte eine nutzen die da ist, allerdings soll diese selbst von der Anwendung überwacht werden und daher wäre das suboptimal.
Edit2: Ich bin übrigens Azubi im (noch) 1. Lehrjahr, bin daher noch nicht ganz soweit (ist meine erste größere Anwendung) und bin z.B. nun das erste mal mit Properties in Berührung gekommen. Mit Datenbanken hatte ich sonst bisher nicht so meine Probleme, eine kleine GUI-Inventarisierung mit MySQL-Anbindung habe ich eigentlich ohne großartige Probleme erstellt. Wenn also noch weitere Angaben benötigt werden sollten, bitte mitteilen
